This field determines the size of the block above the base address that is enabled by
the chip select.
Contain parameters that support bootstrap operations from peripheral memory devic-
es. Bit and field definitions for CSORBT and CSOR[0:10] are the same.
Synchronous mode cannot be used with internally generated autovectors.
The value in this field determines whether a select signal can be asserted.
This field causes a chip select to be asserted only for a read, only for a write, or for
both read and write.
This field specifies the source of DSACK in asynchronous bus mode and controls wait
state insertion.

0 = Asynchronous mode selected
